GAS-SAVING ATTACHMENT FOR HEATING TOOLS. No.1'79,330.

Patented June 27,1876.

UNITED STATES PATENT THOMAS MoKEE,'OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 179,330, dated J one.27, 1876; application filed May 29, 1876.

To all whom it may concern:

Be it known that I, THOMAS McKEE, of the city of New York, in the countyof New York and State of New York, have invented a certain new anduseful Gas-Saving Machine;

and I do hereby declare the following to be a v casin g a lever andspring attached to the cock,

which is operated on by the pressure of a tool laid 011 for the purposeof heating the weight or pressure of said tool, turning on the gas aslong as required to heat the tool. Upon the pressure being removed, thespring turns off the gas, leaving only a faint glimmer, sufficient tokeep the gas alight till required again, thereby causing a saving of gasto the extent of three hundred per cent., and a saving of time also,since the machine is self-acting, and requires no attention to turn thegas ofl' and on.

This invention has relation to the means for heating various kinds oftools by the use of a gas-jet, and has for its object the saving of gasby causing it to flow, only when a tool is being heated, and to beautomatically shut 05 as soon as the tool is removed.

This invention, accordingly, consists in the novel construction of adevice or stand containing a lever, spring, &c., and applied to agas-burner in such a manner that as soon as a tool is laid upon thestand the gas will be turned on by the weight of the tool acting uponthe valve through its connections, and that as soon as said tool isremoved the gas will be turned down through the action of the spring,all as hereinafter described.

Referring to the drawings, A designates a stand of any desirable shape,and adapted to I be secured to or sup orted upon a bench, table, orother support. B B are forked standards rising from said stand toreceive the tool, such as a soldering-iron or the like. 0 represents agas-pipe rising at one end of, and, if desired, through the-base of thestand, and provided with a burner, c, and cock at. D is a hori zontalshaft, forked at one end to grasp the cock, and journaled to one end ofthe stand. A crank, e, connects this shaft with a lever, g, whichextends upward across the recess or fork of the standard B at one sidethereof. This lever is notched at h for the engagement of a dog, '6. Aspring, 70, supported by a stud or arm, l, is arranged to bear againstthe crank, and operate in turning the shaft. The dog is intended toresist the tendency of the lever to move too far toward the center ofthe fork and obstruct the passage of the tool.

The operation will be easily understood. When a heavy tool is placed inthe forked standards, the lever is forced to one side, causing the shaftto be turned through. the medium of the crank, which, at the same time,compresses the spring. By this motion the cock is turned, and the gas,already lighted, is raised. Upon removing the tool the spring reversesthe shaft, turning down the gas and preventing waste.

Having described my invention, I claim The combination, with thetool-stand A, of the lever'h and shaft D, constructed and operatingsubstantially as described, to raise and lower the gas from a burner byturning the cock 0, when a tool is placed on and removed from the stand,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of May, 1876.
